Andrew (or Anderobot Neutralization De-evilized Robotic Even Wright) is an Anderobot that first appeared in Diaper Duty 5: Koopa Kid Gets Mad. He was originally a regular evil Anderobot however Professor E. Gadd took him and crafted him so he would be good and could work with the star children for assistance if needed. He looks like Baby Mario but is a lighter gray then a normal Anderobot and has red light eyes.
Andrew had the ability to tell the babies information about things, however he was not playable. During the BETA version of the game Andrew was playable and he had the power to fly and of lazier vision, powers that were removed in the final version.
At the end of the game when all of the other Anderobots are shut down so is Andrew, he is presumed dead until he was revived in Diaper Duty 10: Koopa Kid's Revenge. Here he had become a slave for Baby Mario.
Andrew is programed to serve Baby Mario and the other star children and thus has a very good relationship with the young baby however at the start of Diaper Duty 10: Koopa Kid's Revenge Andrew had turned into a slave and began to dislike Baby Mario.
Andrew was retooled to be good by Professor E. Gadd and thus likes him very much. He is willing to do anything that E. Gadd says, his voice is the only thing that can overpower Andrew's programming.
